Operating System

An operating system, or OS, is a common computer piece in the world today. An OS is an intricate set of software programs that helps organize information within a computer’s hardware. Every general-purpose computer must have operating system installed on it to run other programs.  
    First, The basic unit. Operating systems provide a software platform (The underlying hardware or software for a system) on top of which other application programs can run. The application program has to be written to run on a specific operating system. User chooses the OS, so that regulates the application possible to run on a system.
     Second, There are four  essential managers of every OS and they all work together like team to get jobs completed. An operating system is simple term it’s chief program that manages all of the hardware and software . It is works as their bass and makes sure they are all working in harmony.   

1.   Memory management is the function that controlling and coordinating memory location and either allocated or free blocks to various programms to optimize overall system performance. There are 4 types of technique ways to manage memory.

1.      Single contiguous allocation

2.      Partitioned allocation

3.      Paged memory management

4.      Segmented memory management

All this techniques has their own advantages on their own. In hardware memory management involves components that physically store data, such as RAM (Random Access Memory ), VRAM (Virtual RAM), GRAM (Graphical RAM), chips, memory caches and flash based SSDs (Solid Star Drives)

           2.  Device manager is Control Panel applet in Microsoft Windows operating system. It allows user to view and control the hardware attached to the computer.Hardware devices typically provide the ability to input data into the computer output data from the computerDevice managment 

does the following activities for device manager keep track of all devices, decides.this process gets the device.allocates the devices in the efficent way de-allocated devices.Device manager important to make sure. It's well designed.

  Device drivers 

  Device detection 

  asynchronous I/O

  Power managment 

  Userspace exposure

  Exciting driver interface

3. File management is organizing and keeping track of files and folders. It helps you stay organised so information is easy to locate and use. Using the file management tools, you can save files in folders with appropriate names so these files can be found or identified easily, create new folders quickly for recognition of information, delete unnecessary files and folders, search for files and folders, create shortcuts of files for quick access and compress files and folders to save space.

4.     Network management is the process of administering and managing the computer networks of one or many organisations. Various services provided by network managers include fault analysis, performance management, provisioning of network and network devices.

5.  The Process manager  is an integral part of any modern-day operating system (OS). The OS must allocate resources to processes, enable processes to share and exchange information, protect the resources of each process from other processes and enable synchronization among processes.

        

          Finally, The OS secures the users files by managing its resource allocation and files, which allow users to comfortably share their computer and networking capabilities with others.
